JOHN COLLMANN, OF SILVER CREEK, ILLINOIS.

RULING-MACHINE.

Specification of Letters Patent No. 10,361, dated January 3, 1854.

To all whom it may concern:

Be it known that I, JOHN CoLLuANN, of Silver Creek, in the county of Stevenson and State of Illinois, have invented a new and useful Improvement in Ruling-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, forming part of this specification, in which-- Figure l is a top view of the box with the cover removed. Fig. 2 is a vertical section upon the line 00 m of Fig. 1. Fig. 3 is a similar section upon the line y 3 of same figure.

Similar letters of reference in the several figures denote the same part of the machine.

My invention refers to an improvement in machines for ruling parallel lines upon copper plates and other surfaces, and has for its object the moving laterally of the way upon which the ruling carriage runs.

It consists in moving the box to which the way is attached, along a bar passing through it, by the action of a cam working against a plate alternately sliding upon and secured to the traversing bar, the operation being performed by means of a lever fastened to the cam, the movement of which is regulated by an adjustable stop, thus limiting the advance of the box and regulating the distance between the lines.

In the drawings a is the box, 6 the way upon which the ruling carriage runs, and 0 the bar passing through and supporting the box. Around the bar 0, and capable of sliding upon it is the case (Z, having between its rear extremity and the partition 6 of the box, the spring wound around the bare.

Projecting from the forward end of the box a, is the ear 9, in which rests the spindle it of the cam m. The face of this cam presses against the plate Z of the case 'cZ. Attached to the cam m is the lever Z, the movement of which is limited by the stop a, which by means of the screw 70 moves backward andforward in the chamber 9. In the side of the case (Z works the screw r so that its extremity shall press against the bar 0, and secure the case to the bar. The operation of my machine is, as follows: The traversing bar 0 is secured at each extremity to uprights, and the stop n adjusted to suit the spaces to be made between the plate 76, moving the box a on the bar 0 a distance proportional to the are passed over by the extremity of the lever Z; this space being as before stated regulated by the screw 7) upon which the stop 11. moves. After the lever Z has completed its movement, the screw r is again loosened, causing the plate is to fly forward by the action of the spring f against the case d, and the other parts to resume the positions assumed on the first loosening of the screw T; which is immediately re-tightened and the lever Z carried forward with the effect before produced; In this manner the operation continues, the screw r being loosened to' permit the action of the spring f, and then tightened to fasten the case (Z to the traversing bar 0, while the box a is movedv the requisite distance by the lever Z. As the box a moves on the traversing bar 0, the way I) is carried forward laterally, and the lining carriage drawn over it in the usual manner after eachmovementof the box a. The box is kept from slipping by means of the springs between the bar 0 and the side of thebox. The slot t in'the side of the box prevents the screwr from interferingwvith the movement of the box In testimony whereof, I have hereunto signed my name before two subscribing witnes'ses.
